Dodge 2011 Dakota - Manual (Page 154)

Automatic Compass Calibration
This compass is self-calibrating which eliminates the
need to manually set the compass. When the vehicle is
new, the compass may appear erratic and the CAL
symbol will be displayed.
After completing one 360 degree turn with the vehicle
traveling less than 5 mph (8 km/h) in an area free from
large metal or metallic objects, the CAL symbol will turn
off and the compass will function normally.
NOTE: Magnetic materials should be kept away from
the Overhead Console. This is where the compass sensor
is located.
Manual Compass Calibration
NOTE: To ensure proper compass calibration, make
sure the compass variance is properly set before manu-
ally calibrating the compass.
If the compass appears erratic and the CAL symbol does
not appear, you must manually put the compass into the
“Calibration” mode.
To Put Into A Calibration Mode
Turn the ignition ON and set the display to “Compass/
Temperature.” Press and hold the RESET button to
change the display between VAR (compass variance) and
CAL (compass calibration) modes. When the CAL sym-
bol is displayed, complete one 360 degree turn in an area
free from large metal objects or power lines. The CAL
symbol will turn off and the compass will function
normally.
Compass Variance is the difference between magnetic
North and geographic North. In some areas of the
country, the difference between magnetic and geographic
North is great enough to cause the compass to give false
readings. If this occurs, the compass variance must be set
according to the Compass Variance Map.
